Subject: RE: Working Group Last Call for "Signaling Entropy Label Capability and Entropy Readable Label-stack Depth Using OSPF" - draft-ietf-ospf-mpls-elc-08

Support.


One question to authors:

On E bit in section 4:  The motivation seems to extend this in Prefix attributes is for inter-area consideration and advertised per every local host prefix (link) .
                                       Is there any specific reason why link MSD is not considered instead ? ( https://tools.ietf.org/html/rfc8491)

Because the intra-area link topology is not exposed across areas or to other protocols.

Thanks,
Acee

We’ve gone through a number of iterations with these ELC drafts and I believe they are ready and meets all the use case requirements. Note that “Entropy Label for Spring tunnels” – draft-ietf-mpls-spring-entropy-label-12 is on the RFC editor’s queue.
This begins a two week last call for the subject draft. Please indicate your support or objection on this list prior to 12:00 AM UTC on Sept 14th, 2014.
Thanks,
Acee
